How is metrics aggregation different from log aggregation? Can’t logs include metrics? Can’t log aggregation systems do the same things as metrics aggregation systems?

If you lurk around enough audiophile-related sites, you may stumble upon writers claiming a difference in sound between the same music played back in FLAC or WAV format. This article on The Well-Tempered Computer does a nice job of exploring this concept, both from the perspective of those who don't believe such a thing is possible and from those who think there is a difference.

On the Linux command line, you work with several types of files, for example, directories, symbolic links, and stuff like that. Sometimes, the requirement is to know more about individual elements in a path - what type of file it is, who is its owner, and more. Thankfully, there's an inbuilt Linux command line utility - dubbed namei - that lets you fetch this information.

If you're a Linux user and have been for years, sometimes you can forget that much of the desktop world is still on Windows. Or perhaps it's not so hard to remember. Many of us hold day jobs where we're not lucky enough to be able to choose our own operating system and are stuck with whatever IT has gifted us. Or, perhaps, you still keep an old Windows PC around for running that one application that just isn't available on Linux.

I don't know where to begin—and I mean that in a very positive way. I can best describe Valley of Genius: The Uncensored History of Silicon Valley (As Told by the Hackers, Founders, and Freaks Who Made It Boom) as a "literary documentary". The book provides a sort of oral history of the Valley from the legends who built it.

I want to show you how to use Netplan on Linux, to configure a static IP address and a DHCP address. I’ll be demonstrating on Ubuntu Server 18.04. I will give you one word of warning, the .yaml files you create for Netplan must be consistent in spacing, otherwise they’ll fail to work. You don’t have to use a specific spacing for each line, it just has to remain consistent.

It can create feelings of fear and shame, foster power imbalances, and cause us to devalue others. read more

Man pages in Linux is the go to spot for first-level support when it comes to command line utilities. As most of you would know, you just write 'man [command-name]' and the corresponding man page pops up. But do you know the path where these man pages are searched for?

I first used and contributed to free and open source software in 1993, and since then I've been an open source software developer and evangelist. I've written or contributed to dozens of open source software projects, although the one that I'll be remembered for is the FreeDOS Project, an open source implementation of the DOS operating system. read more
